The cockpit door is listed in our (SAS MD-80/90 AOM) MEL list.There it says that all door functions must be operative.It does not have a Category A,B or C status determining for how long a defect can remain before it has to be fixed,so a cockpit door with a defect is a "no-go" item.
The door opening during take-off is a fairly normal event.Usually it hasn't been closed properly.

A 737 MEL here in the USA mentions:
52-8 Flight Deck Door Lock Solenoid
May be inoperative provided:
A.The door can be locked and unlocked manually
Thus, the door isn't deferrable, but the electric latch is. The back-up system for manual locking/unlocking is a good old-fashioned bolt latch, here anyways...
FBU is quite correct that thse doors sometimes pop open. The reason nobody seems concerned is that (1) pilots are obviously not going to initiate an abort for one, and (2) the forward F/As are not going to slam it shut so as not to startle the flightcrew with a sudden noise from behind them when they least expect it on takeoff roll. Sort of a distraction...

A locking flight deck door is a must have item. A broken, missing or malfunctioning door/lock is a no-go item. I personally have seen an otherwise perfect aircraft sit for over twelve hours waiting for door lock parts.
